This = Not good

Graphics chipset problem.

A) Graphics chipset is overheating.

1) Suggest clean inside of laptop out,

2) Apply new Thermal Paste to CPU, (Processor), and also carefully peel off the Thermal Pad on graphics chipset, and throw away.

Suggest this time instead of using a Thermal Pad again, (Shudder), use a piece of copper sheet that is the correct thickness, and surface area.

Then use Thermal Paste on top if the graphics chipset, and top of copper sheet; before reinstalling Cooling Tube/Heatsink combo.


B) Graphics chipset has overheated, or actually has been overheating; and has now caused a poor contact of graphics chipset; TO motherboard.

Allow me to expand on A and B above.........

First of all.........do I think the graphics chipset is bad?
No sir, I do not.
Proof is that you ARE getting graphics on the LCD screen.
Three images, or not.
(Internal monitor of laptop, OR external monitor)

Referring back to A)

The CPU (Processor) and the graphics chipset, are the two hardware components that give off the MOST heat.

If the laptop is dirty inside, the cooling capacity of the cooling system; has dropped tremendously.

This allows the CPU, and the graphics chipset (GPU), to overheat.
Overheating graphics chipset will do all kinds of strange things.
(Graphically)

What also transpires, is the Thermal Paste dries up.
Looses it's thermal conductivity properties.
A Thermal Pad is a material that is impregnated with Thermal Paste, so you can see how this equates.
It's impregnated Thermal Paste also dries up.

To regress;
The top of a Processor (CPU), and the bottom of the metal plate of the Cooling Tube, that sits on it; are not perfectly smooth.

A magnified view would detail, 'Ridges, Valleys, and Pitholes'.
When the two parts are mated together, Air Pockets are formed.
Air in this case is an Insulator. Not a Conductor.

Thermal Paste fills the above imperfections, and is an Excellent conductor of heat.

Moving on.........

A Thermal Pad is J-U-N-K!
Carefully peel off, and fly it at the cat. (NO, don't! lol!)

Using a small piece of copper sheet, that is the correct thickness; (And width/length), will allow more surface area for cooling. Becomes more passive surface area for cooling.

(The Fan Assembly does not blo-w air on the graphics chipset. More on that in a moment. Therefore it would not be Dynamic cooling. It is Passive cooling )

Let's take a look at the cooling system for the Dell Inspiron M5010, and I feel it will help explain better........

http://www.ebay.com/itm/Dell-OEM-Inspiron-M5010-CPU-Heatsink-K28PW-Fan-DFB451005M20T-AMD-Warranty-/370766328394?pt=US_CPU_Fans_Heatsinks&hash=item565365324a

Scroll down to the three large photos.
The top, or first photo; shows a Top view.
The next photo down shows a Bottom view.
The photo below it shows a detailed view of the finned Heatsink.

Looking at the first photo, or can be said - Top View.....
The black Fan Assembly is at the top.

Note the rectangular area to the Right, of the black Fan Assembly.
This is the Heatsink.

Coming down from it is the curved copper Cooling Tube.
Note the small rectangular copper metal plate, then at the bottom of the Cooling Tube; note the V-shaped Aluminum metal plate.
(V-shape that goes to an odd shape)

Cooling Tube:
Sightly flattened copper tube, sealed on both ends; and filled with Nitrogen.

Has a small rectangular copper metal plate, that sits on the graphics chipset.
Also has an Aluminum metal plate (V-shaped), that sits on the CPU.
(Processor)

Heatsink:
Small piece of aluminum strip, that has Tall, Thin, fins protruding from it, and is rectangular in shape.

Fan Assembly:
Small multi-bladed fan, in a D-shaped shroud.

Working principle:
Heat is absorbed from the Processor, and graphics chipset, by their two respective metal plates.
Then the Cooling Tube absorbs heat from the plates.

The Cooling Tube then transfers the heat to the finned Heatsink.
The Heatsink absorbs the heat, then radiates it away with it's tall, thin, fins.
Air flow from the Fan Assembly, helps carry heat away from the Heatsink's fins.

That small rectangular piece of copper plate, that sits on the graphics chipset; it TOO SMALL in surface area.
The surface area needs to be increased.

This would be accomplished by ADDING a small piece of copper sheet, that is larger in surface area; and is of the correct thickness.
(Approximately 1/16th of an Inch thick, or 2mm)

Using this video to help explain adding more surface area,

http://www.youtube.com/watch?v=JEpnqhRYGLw

Posted for added surface area, NOT re-flowing graphics chipset, BGA surface mount.
Specifically go to -> 08:38

You can get a small piece of copper sheet, from a hobby store.
Thermal Paste is used on TOP of the graphics chipset, AND on top of the small copper piece of metal. Then the Cooling Tube is installed in place.

For additional questions on this procedure, or to have me clarify anything I have stated, please post in a Comment.

Moving on in an added Comment.

Are we talking about the NEC Versa P7200?


Let me see if I have this straight..........

Turns on, just shows a blue screen, then shuts off.

That about it?

Virus?

I would be more inclined to say the laptop is dirty inside.

Air is used to cool the hardware components inside a computer.

Basic cooling system consists of a Cooling Tube, Heatsink, and Fan Assembly.

Cooling Tube:
Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.
Has a metal plate, or plates; attached to one end.

Heatsink:
Small strip of metal that has Tall, Thin, fins protruding from it.
This is mounted to the opposite end of the Cooling Tube, from the metal plate/s.

Fan Assembly:
Small multi-bladed fan sitting in a D-shaped shroud.

Let's look at an example, (Not for yours),

http://www.ebay.com.au/itm/NEW-NEC-Versa-S900-Fan-Heatsink-GC054009VH-8-V1-B492-M-/270295120853?pt=US_CPU_Fans_Heatsinks&hash=item3eeed83bd5

Two views are shown.
The view on the Right is a Top View.

Let's refer to it, with references also to the other view. The Bottom view.

At the bottom you see a rectangular shaped piece of metal, with 4 holes in it. One in each corner.
For this particular model it sits just on the Processor.

Heat is absorbed by that metal plate, and the curved copper Cooling Tube absorbs heat from the metal plate.
The Cooling Tube then transfers the heat, to the rectangular shaped finned Heatsink.

The Heatsink absorbs the heat, then radiates it away with it's Tall, Thin fins.
Air flow from the Fan Assembly, helps carry heat away from the fins of the Heatsink.

If the fins of the Heatsink are blocked off with 'Gunk', and also the fan blades; the laptop overheats.
['Gunk' = Dirt, dust, hair, lint, food crumbs,....you name it ]

This is an example of a laptop that is dirty inside,

http://www.youtube.com/watch?v=AkAeE5I5E_A

You can see this model has 3 Cooling Tubes, and metal plates; plus 3 Heatsinks.
(0:46)

When a Processor overheats it turns off. (BIOS turns it off)
This is a fail-safe feature that is built-in.
Keeps the Processor from burning up.

Also the Thermal Paste dries up from overheating.
And Thermal Pad.

(A Thermal Pad is a material that is impregnated with Thermal Paste)

Thermal Paste is used on top of the Processor, most of the time.
Other times a Thermal Pad is used instead.
A Thermal Pad is generally used on a graphics chipset.

Is the laptop clean inside Tim? Don't believe this to be the problem, but it would add to the problem.

I also don't think it's a problem with power saver settings.

I suggest it is the problem that plagues Pavilion dv2000, Pavilion dv6000, and Pavilion dv9000; series of Notebook PC's.

Inadequate cooling for the graphics chipset.

The cooling system for your laptop consists of the Heatsink, Cooling Tube, and Fan Assembly.

The Cooling Tube is a slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.
It has two metal plates on one end of it, of copper; with one sitting on the Processor; the other on the graphics chipset.
The other end of the Cooling Tube is connected to the Heatsink.

The Heatsink is a rectangular shaped finned object. It is a small strip of metal that has Tall, Thin, fins protruding from it.

The Fan Assembly consists of a small multi-bladed fan, in a D-shaped shroud.

The two metal plates absorb heat from the Processor, and graphics chipset. The Cooling Tube then absorbs the heat from the metal plates.

The Cooling Tube transfers the heat up to the finned Heatsink.
The Heatsink absorbs the heat, then the heat is radiated away with the tall, thin fins.

Air flow from the Fan Assembly helps carry heat away from the Heatsink's fins.
(The Heatsink is mounted, next to the flat side of the D-shaped shroud of the Fan Assembly. The exhaust side. The intake side of the Fan Assembly is on the Bottom of the laptop)

http://www.ebay.com/itm/hp-pavilion-dv9000-laptop-motherboard-intel-1-6ghz-working-with-hdmi-out-/150984990402?pt=Laptops_Nov05&hash=item2327681ec2

Here you see the black Fan Assembly at the upper right corner.
Although hard to discern, (Even with Ebay mouse zoom in feature), the black rectangular finned Heatsink is to the right of it.

The curved copper Cooling Tube curves to the left.

Put your mouse cursor in the middle of the photo. Go along the Cooling Tube.

Coming away from the Fan Assembly on the Cooling Tube, the dark green square object you see on the motherboard, and under the Cooling Tube, is the graphics chipset.

It is an Nvidia GeForce Go 6150.
Another look at the graphics chipset,

http://www.ebay.com/itm/NEW-Original-nVIDIA-Geforce-NF-G6150-N-A2-BGA-ic-chip-north-bridge-Chipset-/271010886762?pt=LH_DefaultDomain_0&hash=item3f1981f46a

See that small rectangular copper tab that comes off the Cooling Tube, and sits on the graphics chipset?
Too SMALL in surface area.

Allows the graphics chipset to overheat.

Another look at the Cooling System, this time not mounted.
Both Top View and Bottom View are shown,

http://kbsinc.com/438606-001-hp-pavilion-dv9000-cooling-fan-and-heatsink.html

The graphics chipset is mounted to the motherboard, with a BGA surface mount.
Instead of contact pins on the bottom of the graphics chipset, there are Solder Balls.
The mating area of the motherboard has matching Copper Pads.
(Which are also gold plated)

The graphics chipset is set onto the motherboard, with it's Solder Balls lining up on the matching Copper Pads.
Heat is applied at a specific temperature, and length of time.
The Solder Balls melt, and this solders the graphics chipset to the Copper Pads.
(Which in turn mounts the graphics chipset TO the motherboard)

Due to repeated overheating the solder joints (connections) made, start to partially melt.
When the graphics chipset cools down, (Laptop off), the solder joints then re-harden.
This causes Cold Solder Joints, and a poor contact of graphics chipset to motherboard.

Means;
1) Graphics chipset needs to be reflowed.
2) More surface area needs to be added, to that small metal plate on the Cooling Tube, that sits on the graphics chipset.

The following video is posted just for reference. Not advertising for video poster,

http://www.youtube.com/watch?v=bnkQNmKauEc

Here you see more surface area being added.
The best method of Reflowing, however; is to use a BGA Rework Station,

http://ersa.com/art-ir-pl-650-346-1472.html

Scroll down, click on the Red -
Take a few minutes to view the IR 650 demo video

Shows you more detail on the BGA surface mount, also.
I would suggest finding a shop that has a BGA Rework Station, or can send to a shop that does have one.

Any other type of re-flowing is a TEMPORARY repair.

Also, do not add more surface area to the small metal plate on the Cooling Tube, for the graphics chipset; and you will be back to the same problem.

wafy_m, the problem can be attributed to the graphics chipset, is lifting off of the motherboard.
The mounting has loosened.

This is because the cooling system for the graphics chipset, is inadequate.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit

The graphics chipset is the GPU,

http://en.wikipedia.org/wiki/GPU

The mounting of the GPU to the motherboard, is done with a BGA surface mount,

http://en.wikipedia.org/wiki/Ball_grid_array

To explain a BGA surface mount, compare to an older Intel Pentium 4 processor, that uses a Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

The Processor has contact pins on the bottom. 478 of 'em.
The Socket 478 processor socket has matching socket holes.

With a BGA surface mount there are no contact pins, nor socket holes.

In place of the contact pins there are Solder Balls.
In place of the socket holes there are Copper Pads.
(Which have a gold plating on them)

The graphics chipset is set into place over the motherboard, with it's Solder Balls lining up on the motherboard's matching Copper Pads.

Heat is then applied at a specific temperature, and length of time.
The Solder Balls melt, which solders the graphics chipset to the Copper Pads.
(Which in turn solders the graphics chipset to the motherboard)

With the inadequate cooling for the graphics chipset, after time the solder connections will begin to partially melt.

This leads to a poor contact of the graphics chipset to the motherboard, and the problem you are having.

As previously stated the cooling system for the graphics chipset, is inadequate.

Cooling System:
The cooling system consists of a Cooling Tube, Heatsink, and Fan Assembly.

The Cooling Tube is a slightly flattened copper tube, filled with Nitrogen, and sealed on both ends.

Towards one end of the tube is an aluminum plate. This plate sits on top of the Processor. Has four screws through it. Removing these screws removes the cooling system assembly.

Coming up the tube a little bit, is another aluminum plate. This one is smaller, and sits on top of the graphics chipset.

Connected at the opposite end is the Heatsink.
The Heatsink is a small thin piece of metal, with Tall, Thin, fins protruding from it.

Next to the Heatsink is the Fan Assembly.
The Fan Assembly, is a Fan inside of a cage, or shroud.

Draws air up from the bottom of the laptop, and pushes it through the Heatsink's fins, and out the side of the laptop.

Heat from the graphics chipset, and the Processor, are absorbed by their metal plates.
The Cooling Tube absorbs heat from the two aluminum metal plates.

The Cooling Tube transfers the heat along up to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with the Tall, Thin fins.

Airflow from the Fan Assembly, helps to carry heat away from the fins of the Heatsink.

The surface area of the metal plate on top of the graphics chipset, is too small. It is inadequate in surface area size.

The one on the Processor is barely adequate.

http://www.youtube.com/watch?v=bnkQNmKauEc&feature=relmfu

The above is posted for reference. Pause the video at 7:43 to see the cooling system I described above.

1) Black Fan Assembly to the upper left.

2) To the immediate left side of the Fan Assembly is the Heatsink.
Black in color, slightly rounded outside edge, goes along the full length of the left side of the Fan Assembly. Hard to discern the fins.

3) The aluminum X shaped piece with 4 black screws in it, on the copper Cooling Tube, is the metal plate for the Processor.

4) Coming up the copper Cooling Tube towards the Fan Assembly, is the second aluminum metal plate. It is shaped sort of like an S, with flat ends. This plate sits on top of the graphics chipset.

Solution?
Properly remelt the solder connections of the graphics chipset, to the copper pads.
Add surface area to the Processor's metal plate, and the graphics chipset's metal plate.

PROPER method is to use a BGA Rework Machine. Performed by a shop who has one.

ANY other method may is less than. The procedure may last a week, a month, or maybe longer.

There was a recall on this series of Notebook PC.
It is over,

Hello
The Wi-Fi cad inside has shorted. Replace it.

There was a recall on the Pavilion dv9000 series of Notebook PC's. This has passed.

http://www.nvidiasettlement.com/index.html


The problem is the graphics chipset COOLING.

To be more specific, it isn't a problem with the graphics chipset itself, (Nvidia), it is the COOLING of the graphics chipset.
HP's problem.

Allow me to explain, and show you the cooling system for the Pavilion dv9000 series of Notebook PC's; (If you are not familiar)

1) Chipset:
Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_Circuit

2) GPU:
The Graphics Processing Unit, or GPU, is the graphics chipset,

http://en.wikipedia.org/wiki/GPU

The GPU for the HP Pavilion dv9815nr is an Nvidia GeForce Go 7150M,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01394734&tmp_task=prodinfoCategory&cc=us&dlc=en&lang=en&lc=en&product=3689893

3) The cooling system consists of the Fan Assembly, Heatsink, Cooling Tube, and Thermal Paste.

The Cooling Tube is a slightly flattened copper pipe, sealed on both ends, and filled with Nitrogen gas.
It has two metal small plates attached to it.

One small metal plate sits on top of the Processor. The other small plate sits on top of the GPU.

Heat is absorbed by the small metal plates, and then absorbed by the Cooling Tube, from the plates.

Heat is then transferred to the Heatsink. A thin, small metal plate, with Tall, thin fins protruding from it.

The Heatsink absorbs the heat from the Cooling Tube. Then heat is radiated away from the Tall, thin fins.
The air flow from the Fan Assembly helps to carry heat away from the fins.

The small metal plate that sits on the GPU is too Small.
The small metal plate that sits on top of the CPU (Processor) is barely adequate in surface area size, also.

This means the GPU will overheat. With constant overheating the mounting of the graphics chipset, (GPU) will loosen.

The graphics chipset is mounted via a BGA surface mount.
Allow me to explain the BGA surface mount;

Compare to an older Pentium 4 desktop computer processor, that uses a Socket 478 processor socket.

The processor has 478 contact pins on the bottom side.
The processor socket has 478 matching socket holes.

With a BGA surface mount there are no contact pins, nor socket holes.
Solder Balls take the place of the contact pins, and Copper Pads take the place of the socket holes. (Or Processor socket)

The chipset is set into place, with the Solder Balls lining up with the matching Copper Pads.
Heat is then applied at a specific temperature, and length of time.

This melts the solder balls, and solders the graphics chipset to the copper pads. (To the motherboard)

With constant overheating the solder connections start to partially melt.
This creates poor contacts.
This is what you are seeing.

This video explains, and shows the problem. (Also the cooling system)

Problem?

Hardware issue.

Inadequate cooling for the GPU.
Graphics Processing Unit, or graphics chipset,

http://en.wikipedia.org/wiki/GPU

[ Chip and Chipset are slang terms for I.C.
Integrated Circuit,

http://en.wikipedia.org/wiki/Integrated_circuit ]

The GPU for the Pavilion dv9000 series Notebook PC's, is an Nvidia GeForce Go 7150M,

http://en.wikipedia.org/wiki/Comparison_of_Nvidia_graphics_processing_units#GeForce_Go_7_.28Go_7xxx.29_series

To explain further,
A) Starting with the inadequate cooling for the GPU:

http://www.laptopneeds.com/parts/show/110794324214/HP-Pavilion-dv9000-dv9600-AMD-CPU-Heatsink--Fan-Assembly-450863001

The above link shows the Cooling System for the dv9000 series of Notebook PC's.

Looking at the top photo you are looking at a top view;

1) The black Fan Assembly on the left top,

2) The finned black Heatsink, which is on the bottom of the Fan Assembly.
{The Heatsink cannot be viewed very well in this photo.
It is a rectangular object composed of thin fins, attached to a plate of metal.

The length can be seen by the two tabs at either end. One tab sticks out on the left side, and the other tab sticks out of the right side. Each has a hole in it.

The thin fins cannot be seen. They are running in a vertical position, in this photo }

3) The curved copper Cooling Tube. (Slightly flattened copper tube sealed on both ends, and filled with Nitrogen )

4) The Cooling Tube metal plates. A type of Heatsink.

Looking at the top photo, view the aluminum looking metal plate to the right, that resembles a square inside an X.
This metal plate sits on top of the Processor.

Looking to the left along the Cooling Tube, and coming away from the processor's metal plate, is another small aluminum looking metal plate.
This small square metal plate, protrudes out of the side of the Cooling Tube.

This metal plate sits on top of the GPU.
It's size is too small for the job. Inadequate cooling surface area.

Heat from the GPU, and the Processor, is absorbed by the individual metal plates, which sit on top of them.
The heat is then absorbed by the copper Cooling Tube.

The Cooling Tube transfers the heat along it, to the Heatsink.
The thin, tall fins of the Heatsink absorb the heat, then radiate it away.
(Much like a radiator used in a home, or a car radiator)

The Fan Assembly pushes air through, and around, the tall, thin fins of the Heatsink, and helps to carry heat away from the fins.

B) BGA Surface Mount:

To explain the BGA surface mount;
Compare to an older Intel Pentium 4 processor, and it's Socket 478 processor socket,

http://en.wikipedia.org/wiki/Socket_478

The flat bottom of the Processor chipset has contact pins, which protrude out. 478 of them.
The Socket 478 processor socket has 478 socket holes, to match.

With a BGA surface mount there are no contact pins, nor socket holes.
The GPU chipset has Solder Balls on the bottom.
The motherboard has matching Copper Pads.

The GPU's solder balls are lined up with the motherboard's copper pads. Then heat is applied at a specific temperature, and length of time.
The solder balls melt, which in turn solders the GPU to the copper pads.
(In turn soldering the GPU to the motherboard)

With the inadequate cooling for the GPU, the GPU overheats.
Constant overheating one day leads to the solder connections partially melting.
Poor contact is made from the GPU to the motherboard.

I'm going to assume it was yourself, or someone besides a tech, who installed this motherboard.
A tech would have the machine working before giving it back.

A) What was the original problem? Why motherboard replacement?

B) Do you know for a fact that the replacement motherboard is a good working unit?
Bought from a reputable dealer, or history of motherboard is known?

C) Did you follow Anti-Static Precautions, and used a ESD wrist strap, and connected it's alligator clip to a good ground source?

D) How acquainted are you with the design of a laptop's cooling system?
Aware of the basic design?

1) Air is drawn in for the cooling system usually from the Bottom of the laptop.
(Air Intake Duct. It is expelled through the Exhaust Port)

2) The air is drawn straight up into the cooling Fan.
Air then is pushed through the fins of the Heatsink

There is a Cooling Tube usually made of Aluminum or Copper. One end is attached to the finned Heatsink.
The other end is usually attached to a small metal plate.
This metal plate sits on top of the Processor.

Heat from the Processor is absorbed by the small plate. The heat is then transferred to the Cooling Tube. (Cooling Tube absorbs heat from the small plate)

The Cooling Tube then transfers the heat to the Heatsink.
The Heatsink absorbs the heat, then radiates it away with the tall, thin fins.
Air going through the fins, and around the fins, helps to carry the heat away.

Also on the same end as the Processor, is usually another small metal plate. This plate sits on top of the GPU.
Graphics Processing Unit, or simply stated as the graphics chipset.
(Essentially the 'Graphics Engine')

The Processor, and the GPU, are the TWO hardware components that PRODUCE the most HEAT.


Example of basic laptop cooling design I referred to above,

http://www.insidemylaptop.com/disassemble-hp-pavilion-dv6-laptop/

Scroll down to Step 29.
Here you see the black Fan Assembly.
To the immediate left of it is the finned Heatsink. Black in color, fins are not visible.

Coming down on the left from the Heatsink is a copper Cooling Tube.
Most of it's length is attached to an aluminum plate.
(Three machine screws hold the plate to the motherboard)

The aluminum plate you see is covering the top of the Processor, and also the GPU sitting next to it.

Point?
In looking at the Heatsink/Fan/Cooling Tube combination, for the HP Pavilion dv8000 series of Notebook PC's, I do not see a metal plate for the GPU.

I only see that the Processor is covered by a metal plate.

Examples;

1) http://www.pchub.com/uph/laptop/423-55686-4713/HP-Pavilion-dv8000-Series-Cooling-Heatsink.html

2) http://cgi.ebay.com/HP-DV8000-8100-8200-Heatsink-Fan-Assembly-403826-001_W0QQitemZ280451159745QQcmdZViewItemQQptZLH_DefaultDomain_0

Heatsink with copper Cooling Tube attached, and small metal plate at the end for the Processor,

3) http://www.laptoppartsexpert.com/i-5846952-cpu-heatsink.html

4) Motherboard,

http://www.global-motherboard.co.uk/hp-motherboard/HP-Pavilion-DV8000-Motherboard-403835-001.html

This means there is no cooling for the GPU, except for air that may make it's way around, in the inside of the laptop.

Point?

A GPU is mounted to the motherboard with a BGA Surface Mount.
Ball Grid Array.

To explain a BGA surface mount;

Your motherboard has an AMD processor socket (Mobile) that an AMD processor fits in.
The socket has the socket holes, and the Processor has the contact pins, which go into the socket holes.

With a BGA surface mount there are no contact pins, or socket holes.
There are Copper Pads, and Solder Balls,

http://en.wikipedia.org/wiki/Ball_grid_array

The bottom of the GPU chipset has Solder Balls.
The surface of the motherboard has matching Copper Pads.

The GPU is set into place with the Solder Balls lining up, to the matching Copper Pads on the motherboard.

Heat is then applied at a certain specific temperature, and length of time.
The Solder Balls melt, which solders the GPU to the motherboard.
(Solders the GPU to the Copper Pads on the motherboard)

IF, a GPU constantly overheats, the solder connections start to melt. This creates cold solder joints, and a black display on the laptop's internal monitor.

To summarize;

A) The motherboard that has been installed may have the same problem as the original one, if the problem was poor contact for the GPU.

B) If you did not follow Anti-Static Precautions, there's a good chance the motherboard is now an expensive paperweight, or doorstop.

From a quick search just now, (Acer Aspire 5600 processor fan), here is one example,

http://www.laptopcpufan.com/acer-aspire-5600-laptop-cpu-cooling-fan-p-35.html

Here is a link to a free Service Manual for the Acer Aspire 5600 series of Notebook PC's,
(Of which the Acer Aspire 5601WLMi Notebook PC is one of the series),

http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer

In the 'paragraph' that begins with Aspire 1200, go down to the 8th line.
Left-click on - 5600

This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
[ I don't know what version it is, but if it isn't Adobe Reader X {10} I would recommend going to Adobe Reader Support, and downloading it,

http://www.adobe.com/support/reader/

Left-click on the Get Adobe Reader, in the small rectangle under the heading Download.
(Has a white Adobe Reader icon, in the red square to the left of, Get Adobe Reader ]

After you click on the file name (5600), it may take up to 30 seconds before you will see the first page come up. (Sometimes a little longer)
It may also take additional time for the file to fully download.

You can save this PDF service manual to your computer.
This way you won't have to download it again, and can burn it off to a CD for safekeeping.
(You can also delete it from your computer after saving it to a CD, and save harddrive space)

If you do not know how, and would like to, please post in a Comment.

BEFORE you begin replacing:

1) Observe Anti-Static Precautions

Your body carries Static electricity. Static WILL fry out (Short Circuit) the delicate hardware components inside a computer.
Buy, and wear an ESD wrist strap, connect it's alligator clip to a good ground source.

{Electro Static Discharge.
I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.
You may not have such an animal available. Place a large metallic object up on your workbench, (Table), and connect to it. A large metal serving tray, or large metallic knickknack.

If the table has metal legs connect to one of them. (Unpainted surface, remember)
DO NOT work on a bed, couch, or directly on a carpet floor. These are HIGH areas of Static electricity.

2) Use a multi-compartment container for the various screws you will remove.
Label each compartment for the area the screw/s come out of.

If a multi-compartment container is not available, (Weekly pill dispenser/container?), use a clean egg carton as a substitute.
Label each egg holder.

Some screws look VERY similar to other screws. DO NOT mix them up.


3) Make a record during disassembling.
It's nice to have a personal record to refer back to in case you are interrupted.

It's also nice to have a personal record to use along with a service manual.
Make sure your notes are legible so you can read them later. Don't get in a hurry.
Make notes, and drawings, and/or use a digital, or video camera.

{Remember to tilt the motherboard when reinstalling. The I/O ports go down into the case first, then set the motherboard down in flat}

While you're in there, use Q-tips, a small soft brush, (Makeup brush?), and a can, or two of compressed air for computers, and clean that baby out.
Pay special attention to the Heatsink, and Fan Assembly.

Note*
The top of the Processor, and the matching flat plate on the Cooling Tube, have thermal paste in-between them.
Same with the top of the GPU, and it's matching flat cooling tube plate.

After time thermal paste dries up. It loses it's conductivity properties then.
If a laptop has been constantly overheating, it may behoove you to replace the thermal paste.

For proper procedures in performing this, post in a Comment.


To explain GPU:
Graphics Processing Unit. The graphics 'engine'.
A Chipset,

Chip and Chipset are slang terms to denote I.C.
Integrated Circuit,

This is an article on disassembling an Acer Aspire 5610z Notebook PC.
Using it to show the cooling system for your Aspire 5601, which if memory serves is the same, or very close to the same,

Scroll down to Step 7.
The silver looking D shape, and the black fan is the Fan Assembly.
The silver looking D shape is the Fan Shroud.

The slightly flattened curved copper tube is the Cooling Tube.
(The sealed copper Cooling Tube is filled with Nitrogen)

At the top of the Fan Shroud, and where the copper Cooling Tube connects, is the copper, finned Heatsink.
It is barely visible in this photo.

Coming down the curved shape of the copper Cooling Tube is a flat plate. It has an aluminum X on it.
The Processor sits under this plate.

Further down at the end of the Cooling Tube is a small square copper plate.
The GPU sits under this plate.

Air is drawn into the Fan Assembly from the bottom of the laptop.
The air then flows into the copper, finned Heatsink.

Heat is absorbed by the flat plate sitting on top of the Processor's case, and the top of the GPU, and is absorbed by the Cooling Tube.
Heat is then transferred by the Cooling Tube up to the Heatsink.

The fins of the Heatsink radiate the heat away.
The air flow from the Fan Assembly helps to carry heat away from the fins.

It could be that the quality of the fan's bearings in the Fan Assembly, were below par from the factory.
It could be also that the laptop has been dirty inside for quite a while, and this led to the demise of the fan's bearings.

Laptops need to be cleaned inside on a regular basis as needed.
Depends on the environment they are in as to how often.

This sounds like an overheating problem between the processor and graphics card. There's not a whole lot to do except consider using a laptop cooler (sits underneath the laptop), or if you feel confident enough to take it apart, and clean the dust away from the ventilation ports and fan.

It could also be the video card is going bad, as it sounds like it is crashing due to a hardware failure, which could be overheating, motherboard problem possibly, etc.. I suggest if you have warranty on the laptop to send it in for repair.
